RADIATOR.

Application filed .April 12, 1922. Serial No. 552,026.

This invention relates to a radiator for use in connection with an internal combustion engine to cool the cooling medium of the same. It has tor one object to provide a radiator in which the area of the surface of radiation is very large in proportion to the total size oit the radiator. Another object is to provide a radiator of extreme simiplicity and consequent cheapness ot construction. Other objects will appear rom time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:

Figure 1 is a plan view ot an the radiator;

Fig. 2 is a side elevation of such element;

Fig. 3 is a section taken on line 3 3 ot Figure 1 on an enlarged scale;

Fig. 4 is a diagrammatic illustration showing a radiator made up of the radiator elements illustrated in the previous figures.

Figure 5 is a partialvertical cross section takend on line 5-5 of Figure 4;

Figure 6 is a partial side elevation of the pipe D.

Like parts are designated by like characters throughout.

. The radiator is built up of a plurality of elements, one of which is illustrated herewith. Each of the elements is made from two sheets A A `of sheet metal. tened together preferably at their outside edges A by being crimped together and soldered, although they might be secured together in any other suitable manner. .i ot the sheets of the radiator elements is stamped out in the form shown particularly in Figure l so that when a pair of them is secured together they will produce an eX- tremely long and tortuous passage through which the liquid must flow in passing through the elements. This passage 1s formed by the outwardly pressed portions A2 A2 within which lie the engaging portions A3 A3. Along these engaging portions at considerable intervals are positioned rivets A4 A4 which serve to hold` the sheets together.

Each of the radiator elements is provided with two connection members B B. In Figelement of They are fas- Each ure 3 a section of one of these members is shown on an enlarged scale. Adjacent each of the members the sheets A A are outwardly flared as at B. The member B is cylindrical in section and is provided with a plurality ot' ports-B2 B2. These ports communicate with the interior of the memberB and with the interior of the radiator section and permit the {iow of liquid to and from the section. On one side the member B is provided with ythe outwardly extending flange The outside diameterot this 'flange is the same as the inner diameter of the. opening B* of the member B. By means of this construction any suitable number of radiator elements can be nested together, and in each case the member B will mate with the corresponding member and a complete tubular connection between all of the radiator elements is thus built up from the individual sections which first formy part of each ra-v diator section.

As shown in Figure 4 the radiator elements are assembled to form a complete radiator. The supply pipe C by means of the union C is connected to the upper connection member of the radiator elements as assembled. The elements as shown are held together by the tying bolt C2 which has the enlarged head C2 and the nut C4. Through the supply pipe C liquid enters the upper edges ot the radiator elements and through the ports in their connections passes down and about the passages in each of the elements. A

At the lower end of the radiator a pipe D is inserted. This pipe is of less diameter than the interior of the connection holes in y each of the radiator elements and it is pertorated only adjacent one end as atV D. lVithin the pipe there is positioned a tying bolt E which is similar to the bolt C2 above, and it is also provided with an enlarged head E and a nut E2. In communication with the pipe D is a union F which in turn is connected to a discharge pipe F. By means ot the arrangement shown the iuid enters from the supply pipe and some fluid passes through each of the radiator elements gradually coming to its lower edge and thus yinto the built-up pipe formed of the connection memhers in each of the radiator elements. Since, however, a pipe lies within these elements and since this pipe is perte rated only adjacent the outer end, the tluid must all pass to that end betere it can enter thc pertoration, pass backward through the interior ot the pipe and so out through the dischai'ne pipe. Thus the fluid is compelled to cir( ate through the radiator in a more complete ano perfect fashion than would he the case if the additional pipe at the bottom were lacking; or it this pipe were perforated tl rang-hout its length.

(l is a easingsurrounding` the radiator and provided with an open bottom G1 and a top stach (lf2 shaped lgenerally in the term ot a venturi.

,eilthourh l have shown this radiator as heine` huilt up from sheet pieces out ot which t e elements are stampe?, it will he obvious that this construction might he departed ison'i. and although l have shown the edges crimped tother, it will also he obvious that they r` Iejht he soldered. or welded and that welding` might he suhstituted for rivets in the interior of the passage without departing from the spirit ot my invention. Thus therefore although l have shown an operative form oit' my invention. still it is obvious that many chances both in term, shape and arrangement of parts might he made without departing` 'from the spirit of my invention.

The use and operation ot my invention are as follows:

The sides of the radiator elements are pressed or stamped. rlChey are then assem hled in matiirql pairs with the connection elements secured as shown in the drawings. The radiator proper is then made from a ol the sheets as heine` curled and plurality ot these sections which are fastened together as shown in Figure 1l.
